【问题描述】：

我知道这已经被问过很多次了，但我正在努力优化我们公司的移动网关。这是在 2016 年承包的，但开始建造它的人并不是为移动设备建造它。而他没有完成。现在，请知道我在 ASP.Net 上切了牙，所以 PHP 不是我的强项，但我继承了这个项目来完成它。它是用 CodeIgniter 2.2 构建的，我无法升级它。所有移动设备（我从事的工作）都将使用 Bootstrap（最新版本）构建，因为我喜欢 Bootstrap 以及它使构建“移动优先”的东西变得多么容易。因此，我不想尝试更改他构建的所有布局和文件，因为一切正常，并且在所有浏览器中都显示得非常好，但不适用于移动设备。还知道我已经查看了可以在此处找到的每个示例（SO）。我已经尝试了一切。问题是，我可以显示我的“移动”登录视图，但我不知道从那里去哪里。我是否仅为将要构建的移动页面创建单独的模型和控制器？我将在下面展示我尝试过的示例代码以及有效的方法。有没有人尝试过这样的事情并有一个可行的例子？至少有足够的代码可以为我指明正确的方向？我将不胜感激。在这里绞尽脑汁。哦，是的，我确实从最新版本的 CodeIgniter (3.1.11) 更新了 user_agent 代码以捕获所有最新的移动浏览器，因为我知道 CI 2.2 有点过时了。顺便说一句，我试图提供尽可能多的信息，如果您使用普通计算机访问它会显示常规登录页面并且它可以正常登录。但是，如果您使用移动设备访问，它会显示移动登录页面，但不会登录。只需刷新页面即可。无论我是走 user_agent 路线并使用相同的 URL，还是走 Detect_Mobile.php 路线并加载 mobi.gatewayurl.com 页面。好的，这是主机上的布局。抱歉，我知道这很复杂，但所有这些布局都已经完成，我添加的只是移动和 mobi 目录。

            |--account <== Copied all views from the account directory for regular users in here as well.
            |--templates <== The mobile login page loads by putting in a blank header.php, heading.php, and footer.php in here. Otherwise it throws errors if I don't have these in here.
            |--login.php <== Or I tried even naming it mlogin.php for mobile, but it won't login. It loads, but just refreshes the page.

这是我从SO article 13928677 获得的 MY_Loader.php 文件。

<?php  if (! defined('BASEPATH')) exit('No direct script access allowed');

class MY_Loader extends CI_Loader
{
    //overides existing view function    
    function view($view, $vars = array(), $return = FALSE)
    {
        $CI =& get_instance();

        $CI->load->library("user_agent");

        if($CI->agent->is_mobile()){
            $view = 'mobile/'.$view;// <== This does diplay my mobile login page without changing the URL.
        }

        return $this->_ci_load(array('_ci_view' => $view, '_ci_vars' => $this->_ci_object_to_array($vars), '_ci_return' => $return));
    }
}
//This works good to keep the same URL, such as https://gateway.ourgatewayurl.com, but where to go from here? Otherwise using Mobile_Detect.php, I
//can redirect to https://mobi.ourgatewayurl.com. That would be no problem as well, I can do the subdomain thing, but again, where to go from here?
?>

这里是 login.php 控制器。再说一遍，这不是我写的，它已经完成了。

<?php

class Login extends CI_Controller {

    public function __construct()
    {
        parent::__construct();
        $this->load->library('session');
        $this->load->model('login_model');
        $this->load->model('setting_model');
        $this->load->model('producer_model');
        $this->load->model('company_model');
        $this->load->model('report_model');
        $this->load->model('administrator_model');
    }

    public function index()
    {
        $data['settings'] = $this->setting_model->get_setting();

        $data['bad_login'] = 0;

        if ($this->input->post('username')) {

            $data['login'] = $this->login_model->get_login($this->input->post('username'),$this->input->post('password'));


            if ($data['login'] == '0') {

                $level = $this->session->userdata('user_level');

                if ($level == 'administrator') {

                    $data['message_list'] = $this->administrator_model->get_message();

                    $this->load->view('templates/admin/heading', $data);
                    $this->load->view('templates/admin/header', $data);
                    $this->load->view('administrator/dashboard', $data);
                    $this->load->view('templates/admin/footer', $data);
                    $this->load->view('administrator/leftmenu', $data);

                } else {

                    $data['company'] = $this->company_model->get_company($this->session->userdata('company_id'));
                    $data['producer'] = $this->producer_model->get_producer($this->session->userdata('producer_id'));

                    $data['message_list'] = $this->administrator_model->get_message();

                    $this->load->view('templates/admin/heading', $data);
                    $this->load->view('templates/admin/header', $data);
                    $this->load->view('account/dashboard', $data);
                    $this->load->view('templates/admin/footer', $data);
                    $this->load->view('account/leftmenu', $data);
                }

            } else {

                $data['bad_login'] = 1;

                $data['login'] = '1';
                $this->load->view('templates/heading', $data);
                $this->load->view('templates/header', $data);
                $this->load->view('login', $data);
                $this->load->view('templates/footer', $data);
            }

        } else {
                $data['login'] = '1';
                $this->load->view('templates/heading', $data);
                $this->load->view('templates/header', $data);
                $this->load->view('login', $data);
                $this->load->view('templates/footer', $data);
        }

    }
}
?>

这是 account.php 控制器的一部分。我遗漏了很多。

<?php
//Only showing for index and dashboard, but he has a public function for every page he has on the gateway.
class Account extends CI_Controller {
    
    public function __construct()
    {
        parent::__construct();
        $this->load->library('session');
        $this->load->library('My_PHPMailer');
        $this->load->model('account_model');
        $this->load->model('setting_model');
        $this->load->model('user_model');
        $this->load->model('producer_model');
        $this->load->model('company_model');        
        $this->load->model('email_model');
        $this->load->model('report_model');
        $this->load->model('pagenate_model');
        $this->load->model('staff_model');
        $this->load->model('signup_model');
        
        if (!$this->session->userdata('user_id') || ($this->session->userdata('user_level') != 'corporate' && $this->session->userdata('user_level') != 'branch' && $this->session->userdata('user_level') != 'producer')) {
            
            header("Location: " . base_url() . 'index.php?/login/logout/');
            die();
        }
        
    }

    public function index()
    {
        $data['settings'] = $this->setting_model->get_setting();
        $data['company'] = $this->company_model->get_company($this->session->userdata('company_id'));
        $data['producer'] = $this->producer_model->get_producer($this->session->userdata('producer_id'));
        
        $data['message_list'] = $this->account_model->get_message();
        
        $this->load->view('templates/admin/heading', $data);
        $this->load->view('templates/admin/header', $data);
        $this->load->view('account/dashboard', $data);
        $this->load->view('templates/admin/footer', $data);         
        $this->load->view('account/leftmenu', $data);


        
    }

    public function dashboard()
    {
        
        $data['settings'] = $this->setting_model->get_setting();
        $data['company'] = $this->company_model->get_company($this->session->userdata('company_id'));
        $data['producer'] = $this->producer_model->get_producer($this->session->userdata('producer_id'));
        
        $data['message_list'] = $this->account_model->get_message();

        $this->load->view('templates/admin/heading', $data);
        $this->load->view('templates/admin/header', $data);
        $this->load->view('account/dashboard', $data);
        $this->load->view('templates/admin/footer', $data);         
        $this->load->view('account/leftmenu', $data);
        
    }
}
?>

这是登录模型。

<?php
class Login_model extends CI_Model {

    public function __construct()
    {
        $this->load->database();
    }
    

    public function get_login($username, $password)
    {
        
        
        $this -> db -> select('*');
        $this -> db -> from('user');
        $this -> db -> where('user_email = ' . "'" . $this->db->escape_str($username) . "'");
        $this -> db -> where('user_password = ' . "'" . $this->db->escape_str(do_hash($password, 'md5')) . "'");
        $this -> db -> where('user_is_deleted = 0');
        $this -> db -> limit(1);

        $query = $this -> db -> get();
        
        $user = $query->row_array();
        

        if($query -> num_rows() == 1) {
            
            $this -> db -> select('*');
            $this -> db -> from('user_level');
            $this -> db -> where('user_level_id = ' . $user['user_level_id']);
            $this -> db -> where('user_level_is_deleted = 0');
            $this -> db -> limit(1);        
    
            $query2 = $this -> db -> get();
            
            $user_level = $query2->row_array();         
            
            $pid = '';
            $coid = '';
            $ctype = '';
            
            
            if ($user_level['user_level_name'] != 'administrator') {

                $query2 = $this -> db -> get();
                $producer = $query2->row_array();
                
                $this -> db -> select('*');
                $this -> db -> from('company');
                $this -> db -> where('company_id = ' . $producer['company_id']);

                $query3 = $this -> db -> get();
                $company = $query3->row_array();

                                
                $pid = $producer['producer_id'];
                $coid = $producer['company_id'];
                $ctype = $company['company_type_id'];
                
            }
            
            $newdata = array(
                          'user_id' => $user['user_id'],
              'producer_id' => $pid,
              'company_id' => $coid,
              'company_type_id' => $ctype,
              'user_level_id' => $user['user_level_id'],
                          'user_level' => $user_level['user_level_name'],

            return '1';
        }

    }

对不起，这太长了。我只是想让每个人都看看这是如何布局的，以及他是如何编写代码的。任何帮助将不胜感激。非常感谢。

没关系，我决定将整个东西转换为 Bootstrap。如果我这样做会更好。无论如何都需要。无论如何，Bootstrap 非常适合移动设备。
